“Updated results from the phase II LuPSMA study published in The Lancet Oncology showed radionuclide treatment with Lutetium-177 [177Lu]-PSMA-617 nearly doubled median PSA progression-free survival (PFS) in men with progressive metastatic castrate-resistant prostate cancer (mCRPC) compared with previous results with another radiopharmaceutical, radium-223 (Ra-223; Xofigo).
“In LuPSMA, the median PSA PFS was 7.6 months (95% CI, 6.3-9.0) and 27 (90%) of 30 men experienced PSA progression. The median overall survival (OS) was 13.5 months (95% CI, 10.4-22.7) and 22 (73%) men had died by the November 2017 data cutoff.”
“Priority review of Roche’s supplemental Biologics License Application means the FDA will decide whether or not to approve the therapy within six months instead of the standard 10 months. A decision is now expected by Sept. 5. To be granted priority review, a therapy candidate must show potential to provide significant benefits for the treatment, prevention, or diagnosis of a disease.”
“Freddie Hamdy, MBChB, a leading prostate cancer researcher and head of urology at University of Oxford, blew my mind when I spoke with him the other day.
“He told me we are on the cusp of a revolution in active surveillance (AS) for prostate cancer — one that will in effect ‘cure’ my cancer with a swipe of a pen as cancer will be redefined.
“A prostate cancer diagnosis with a low-risk Gleason 6 changed my life in December 2010. My first urologist offered to rush me to the OR. I declined and got a second opinion. Instead, I opted for AS and have been on it ever since.”
“The use of genetic tests aimed at detecting the presence of mutations in the BRCA1 and BRCA2 genes in women with breast cancer is rapidly declining in favor of tests that can detect multiple cancer-associated mutations, according to researchers at the Stanford University School of Medicine and five other U.S. medical centers.
“Some researchers had wondered whether multigene testing, which may identify genetic mutations of uncertain clinical significance, would lead more women to consider prophylactic mastectomies — a surgery in which both breasts are removed to prevent future cancers — out of an abundance of caution. However, the current study did not show an increase in mastectomies associated with testing more genes.”
“An Independent Data and Safety Monitoring Board (DSMB) unanimously recommended that the Phase 1/2 clinical trial evaluating VBI Vaccines’ VBI-1901 continue to enroll patients with recurrent glioblastoma (GBM) in a second study arm.
“The positive review recommended the study continue without modification, after scanning through all safety data from the first group of patients, who received the lowest VBI-1901 dose. Enrollment now has commenced for the second, intermediate-dose study arm.”
“The U.S. Food and Drug Administration (FDA) recently accepted a supplemental biologics license application (sBLA) and granted Priority Review for atezolizumab (Tecentriq) in combination with bevacizumab (Avastin), paclitaxel, and carboplatin for the first-line treatment of metastatic nonsquamous non–small cell lung cancer (NSCLC). The FDA is expected to make a decision on approval by September 5, 2018.
” ‘Our phase III results showed atezolizumab in combination with bevacizumab, paclitaxel, and carboplatin has the potential to provide a significant survival benefit in the initial treatment of metastatic nonsquamous non–small cell lung cancer,’ said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development at Genentech.”
“The FDA has received a supplemental biologics license application (sBLA) seeking approval for pembrolizumab (Keytruda) in combination with standard chemotherapy as a treatment for patients with metastatic squamous non–small cell lung cancer (sNSCLC).
“The application is based on findings from the phase III KEYNOTE-407 trial (NCT02775435), which evenly randomized 560 treatment-naive patients with metastatic squamous NSCLC to pembrolizumab combined with carboplatin/paclitaxel or nab-paclitaxel (Abraxane), carboplatin/paclitaxel alone, or nab-paclitaxel alone. The coprimary endpoints were overall survival (OS) and progression-free survival (PFS). Secondary endpoints included objective response rate (ORR) and duration of response.”
“Based on data from the phase III COMBI-AD study, the combination of dabrafenib (Tafinlar) and trametinib (Mekinist) has been granted FDA approval for the adjuvant treatment of patients with BRAF V600E– or V600K–positive stage III melanoma following complete resection.
“In results from the trial, adjuvant treatment with dabrafenib and trametinib reduced the risk of relapse or death by 53% compared with placebo for patients with BRAF-mutant stage III melanoma.1,2 After a median follow-up of 2.8 years, the 3-year relapse-free survival (RFS) rate with dabrafenib and trametinib was 58% compared with 39% for placebo (HR, 0.47; 95% CI, 0.39-0.58; P <.001).”
“Carboxyamidotriazole orotate (CTO) in combination with temozolomide (Temodar), with or without radiotherapy, produced positive safety and efficacy results in a phase Ib study of patients with glioblastoma (GBM) or anaplastic gliomas.
“Forty-two patients were divided into 2 cohorts and received treatment. Cohort 1 included 27 patients with recurrent, temozolomide-refractory anaplastic gliomas or GBM. Twenty-one patients were assigned to a regimen of 219 to 812.5 mg/m2 of once-daily CTO in escalating doses and 6 were assigned to a fixed daily dose of 600 mg of CTO. All 27 patients received 150 mg/m2 of temozolomide on days 1 to 5 of each 28-day cycle.”
